Arduino MIDI controller library

Question

I am trying to make a MIDI controller with three buttons (play, pause, and rec), a potentiometer and a fader. I am using this library: https://github.com/tttapa/MIDI_controller

I can't manage to make the buttons do what I want (trigger the play button on my daw).

Also when I tested the potentiometers with Hairless , I got this error:

Answer 1

This seems like a communication error.

The autor recommends to change to the new version . If you want to stay with that version, try tweaking the set speeds on both sides.

The default Hairless baud rate in Arduino is 115,200 symbols/second.

(You could change it in the settings, but I recommend just changing it in Hairless, as I think it is the default.)

 MIDI_controller/src/Settings/Settings.h
     Line 10
  #define HAIRLESS_BAUD 115200

Answer 2

I had the same problem.

Your setup does not provide a MIDI input to the DAW. A DAW can read from a MIDI input but not from a serial port.

The Arduino sends MIDI via serial port to the application "Hairless serial MIDI bridge" and Hairless sends that MIDI data with the correct baudrate to a MIDI input device.

You can use http://www.tobias-erichsen.de/software/loopmidi.html for a MIDI input.

Have a look at https://piecesofpi.co.uk/arduino-usb-midi-the-easy-way/ for details.

Another option may be an Arduino with internal USB (Atmega 32U4) without the need for Hairless and the MIDI loopback (I have not tries this).
